l 3e it known that I, DAVID J AMES VVINN, a c1t1zon of the United Statos, residing at Sum ter, in the county of Snmter and State of South Carolina, have invontod a new and useful Improvement in Shoot-Wletal Roofing, of which the following is a specifioation.

My invention relates to shoot-motal roof ing of that type in which the motal shoots are formod at thoir latoral odgos With an upward and downward bond along said edgos, forming along oach odgo an elevated honsin hoi1sing of one shoot overlapping and fitting closely clown upon tho housing of the adjacent shoot and both boing secnred to the subjacent sheathingboards 0i' tho roofby nails driven into the elovatod ridgos and throngh wooden ribs or filling-strips conf ained there in into the snbjacent sheathing-boards. W'ith this form of roofing tho nail-hoads are exposed, and conseqr entl v there is liable to be loakage through the nailholos.

My invention consists in forming one of the side odges of the shoots With two additional folds arranged to form a rotnrnbend over the ridges, so as to cover and protect tho nails and giving a triple thicknoss oi shoot metal over the ridgos, as horoinaftor filly doscribed with reference to the drawings, in Which Figaro 1 is a face view, and Fig. 2 an edge viow, of one of my improved roofing-sheets; and Fig. 3 is a transverse section taken thr otgh a roof laid With my shoots, tho soc tion being at right angles to the ridgos.

In tho drawings Figs 1 and 2, b reprosonts one of my roofing-sheets. As herotofore oonstructed thoso have boon made simply as roctangular shoots With an upward and clownward bond 1 2 along one latoral edgo and. anothor upWard and downward bond 3 4 along the other latoral edgo, tho bonds 1 2 of one shoot fitting ovor tho bonds 3 4 of the adjacent shoot and being secured by nails drivon along tho apex and into a housod Wooden strip bolow tho bonds to form a solid nailing and the mails boing long onough to pass through thoso filling-strips and into the woodon sheathing a beloW. In

accordance With my invention one of the.

g, tho

lateral edgos 3 4 is formod with two additional folds or bonds 5 6, made in one pioce with and of snbstantially the same Width as 3 4 or a little widor; but thoso bonds have thoir angles revorsed to those of the bonds 1 2 and 3 4. In laying a rooi With those plates after the bonds 1 2 of a shoot have boen laid on top of the filling-strip c (soo loft-hand part of Fig. 3) the bonds 3 4 of the noxt acont plate are placed directly ovor 1 2 of the previouslylaid plate, and nails (shown in dotted linos on the loft of Fig. 3)

are thon drivon through the lapped folds 1 2 3 4 and also through the housod filling-strips c into tho sheathing of Wood, and thon tho additional folds 5 and 6 are bent back and over the nails, tho fold 5 lying fiat clown upon the fold 4 and the iold 6 lying fiat doWn upon the fold 3, as shoWn on tho right-hand side of Fig. 3, in which it will be seon tho nails have bocome eompletoly covered and tho n2til-holes protectod from access of rain. In this oporation tho angular bond ac, Fig. 2, coinoides With and fits over tho angular bond y, making a straight, truo, and undonted ridgo, which adds t0 tho symmotry and beauty of the roof, and the ridgos are of three ply thicknoss, Which stifi'ens thom against pressure from tramping on the same and also strongthons tho roof as against the lifting strains of wind-pr'essure undor tho shoots.

Although I have shown tho body of the plates b as fiat and plain, it is obvious that thoy may be made oorrugatod and stifionod, if desirod.

The roofing-plates are choaply rollod or foldod in one pioce and are compactly nostod togothor for mutual protection and oconomio transportation.

I claim 1. A shoot metal roofing plate having along ono odgo an angular upWard and down 'ward bond and having along tho other odgo four angular bonds, the inner tWo being angular upward and downward bonds and the outer tWo boing bent outward and npwardly and all of the metal surfaces botwoen tho bonds being fiat and substantially oqual sections adaptod to register with oach other as describod.

2. A sheetmetal roofing, comprising, a verse bends being folded over to house and wooden base, sheet-metal plates haVing along cover the mails and subjaqenb lapped folds. each lateral edge &n upward and downward DAVID JAMES -WINN bend and having formed in one pi ece With 5 one lateml edge two reversely-bent folds and Vfitnesses:

nafls or screws passing through the two R. M. FERRY, thicknesses of the two lapped folds, the re- 1 G. L. W'ARREN.
